Overview
NCS37000 Ground Fault Circuit Interrupter (GFCI) Description The NCS37000 is a fully UL943 compliant signal processor for GFCI applications.
The device integrates a flexible power supply (including both shunt and LDO regulators), differential fault, and grounded-neutral detection circuits.
Proprietary impedance measurement and signal processing techniques are used to minimize the number of external components and improve performance.
The device also includes a specialized DSP controller that offers best in class immunity to nuisance loads without the need for external analog filters.
